A-ni-mal! A-ni-mal!
Grover.
I was always torn between Fozzie Bear and Gonzo. Wakka wakka wakka!
Lew Zealand
Cookie Monster.
Cookies aren’t a sometimes food!
I have to admit: I’m a Rowlf fan. Probably his only one, but there you are.
Not sure why, but the Cheefy du Sweedy is the funny laughy fur me. Heejun burgen for de Muppy. Bork bork bork!
You are not alone.
C is for Cookie! That’s good enough for me.
Cookie Monster eating vegetables, sacrilegious!
My favorite was always Statler and Waldorf.
They’re inseparable, so yeah, I listed two 
Rowlf fan here too !!!
Grover
Kermit or Animal.
What can I say, I’m torn between my superego and my id.
Nope. I’m a Rowlf fan as well.
Doctor Bunsen Honeydew. (with Beaker by his side)
Cookie.
Pilot and Rygel…
what? they’re Henson puppets, they qualify, right? 
okay, okay, sticking to the parameters of the OP…
Animal, Swedish Chef, Dr. Bunson Honeydew, Beaker, Sweetums, and Uncle Deadly
…Kermit.
He, like Richie Cunningham on Happy Days, were my early role models…
…which led to a very, very sad childhood, I can tell you!
Bunsen and Beaker.
Strangely enough, my parents once told me I looked like Beaker as a kid.
I started with Animal, when I was maybe 5, graduated to Cookie Monster around 8, and have been a Grover man ever since.
Grover is… humble.
